On 27 February 2010, a massive earthquake of magnitude 8.8 hit Chile and moved the city of ConcepciĆ³n 10 feet to the west. The quake was so strong that it shortened Earth's day and slightly changed the rotation of the planet. However not all earthquakes are headline news, and they are not a rare occurance.
Each year more than 100,000 earthquakes happen, but the majority are too weak to be felt by humans. Most are also concentrated around the fault lines and can be very deep underground or underwater. The USGS provide live data feeds on all seismic activitiy (not only earthquakes, but explosions, quarry blast and ice quakes).
Below you can relive the past 30 days of activitiy from around the world. The magnitude of each blast is represented in both size and color on the map, with a breakdown of the frequency of daily activity for both magnitude and depth displayed below.
